I'm the kind of person who not only has a difficult time lying (my "tell" is unbelievably obvious), but I also don't have much of a verbal filter.
I find myself constantly blurting out things, not all of which are popular opinions, and only afterwards realizing that perhaps I should have tried to keep some of that to myself.
But what can I say? I'm just being honest. And so are all of these people. After all, honesty is the best policy, right?
